  • Experimental Physico-chemical Properties
  • Miscellaneous

    • Chemical Class:

      A dithioloquinoxaline that results from the formal condensation of 6-methylquinoxaline-2,3-dithiol with phosgene. It has been used as a fungicide and acaricide for the control of mites and powdery mil dew on citrus, vegetables, and walnuts, but is not approved for use in the EU. ChEBI CHEBI:34620
